Specification of Letters Patent.

Patented Aug. 26, 1919.

To all whom it may concern:

Be it known that I, LoUIs M. SARTAIN, a citizen of the United States,residing at Coalmont, in the county of Grundy and State of Tennessee,have invented a new and useful Rail-Joint, of which the following is aspecification.

This invention relates to rail joints, one of its objects being toprovide rail gripping elements adapted to be coupled in a novel mannerto the tie plate thereunder and which, when subjected to the weight ofthe engaged rails and of the load thereon, will grip the rails withincreased pressure, holding them tightly against displacement relativeto each other.

A further object is to provide eflicient means for coupling said membersto the plate thereunder, and which allows the membars to be removedreadily when the rail is removed.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claim, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit or sacrificing any of theadvantages of the invention as set forth in the appended claim.

In the accompanying drawings the pre ferred form of the invention hasbeen shown.

In said drawings Figure 1 is a plan view of a portion of a tie platehaving the present improvements in position thereon and engaging andholding rails.

Fig. 2 is a side elevation of the structure, certain parts being shownpartly in section. Fig. 3 is a section on line 33, Fig. 2.

Fig. 4 is a perspective view of one end portion of the tie plate.

Referring to the figures by characters of reference, 1 designates aplate that can be secured on a tie or other structure or that can bepart of a metallic or composite tie.

This plate is adapted to extend under the rails R at the joint and isprovided at each s1de of the joint with upstanding shoulders 2 each ofwhich has a recess 3 extending thereinto. Another recess 4 is formed inthe top of the plate adjacent each shoulder 2 and these recesses 4. areadapted to receive lugs 5 extending downwardly from the free endportions of chair members 6. These members have ears at their innerends, as shown at 7, which are pivotally connected as shown at 8. Jawsare extended upwardly from the chair members close to the pivot 8 andeach of these jaws, indicated at 9, is so shaped as to lap one of thebase flanges of each rail R and to extend toward and into contact withthe webs of the rails. Reoesses 10 are formed in the gripping faces ofthe j aws for the reception of the ends of dowel pins 11 which areextended through holes in the Webs of the rails, as shown. Tongues 12are extended from the outer ends of the members 6 and are insertibleinto the re cesses 3.

In using the device the jaws 9 are swung apart so as to cause the outerends of the members 6 to swing downwardly toward each other. The tongues12 are then inserted into the recesses 3. The rails R with the dowelstherein are placed between the jaws and the weight of the rails,pressing downwardly on the inner or connected ends of the members 6 willcause said members to move downwardly, thereby forcing the tongues 12into the recesses 3, lowering the lugs 5 into the recesses 4 and causingthe jaws 9 to grip the rails tightly and receive the ends of the dowels11. Thus the parts will be locked together securely and the only way inwhich the rails can be unfastened is by raising them and the inner endsof the members 6 so as to swing the jaws apart.

What is claimed is:

The combination with a tie plate having spaced upstanding shouldersprovided with recesses, there being recesses in the plate and adjacentthe shoulders, of pivotally connected chair members having projectingmeans thereon for insertion into the respective recesses When themembers are moved my own, I have hereto affixed my signature olnto theltie platg, rail gripping gaws 1upon in the presence of two Witnesses.tie mem ers, an rail engaging oWe sinsertibleat'theii"eIIdsintothezopposedijews, LOUIS T N N' 5 those: portions oithe members between the: Witnesses;
